FIELD: medicine.SUBSTANCE: present invention relates to a filtering syringe, and more specifically to an apparatus obtained by improving a syringe provided with a filtering means for filtering foreign substances, such as glass fragments of an ampoule, in order to prevent the introduction of said foreign substances together with the liquid medicament and simultaneously enable smooth intake of the liquid medicament and administer it with little effort, in particular, even if a filtering device having micropores is used. Filtering syringe comprises injection needle (10), cylinder (20) and piston (30) and further comprises a suction flow channel formed from a pointed hollow cap (100) to cylinder (20) and equipped with a one-way valve means (300), and an injectable flow channel formed from cylinder (20) to injection needle (10) and provided with detachable opening/closing means (400) for selectively opening and closing needle (10) for injection and filtering means (200) for filtering foreign substances from liquid medicinal agent, in which the channel for the injected flow and the channel for the suction flow have common sections of the flow channels, or the channel for the injected flow is formed independently of the channel for the suction flow, as a result, a section of the flow channel from filtering means (200) to injection needle (10) in the channel for the injected flow is formed independently of the channel for the suction flow.EFFECT: filtering syringe is designed so that filtering agent is provided in channel for injected flow to prevent introduction of foreign substances together with liquid medicament, simultaneously enabling smoother intake of a liquid medicament and introduction thereof, despite using a filtering agent having micropores, thereby leading to maximum convenience for the user and consumer properties of the syringe.12 cl, 18 dwgНастоящее изобретение относится к фильтрующему шприцу и, более конкретно, к аппарату, получаемому путем усовершенствова
